IMPROVEMENT IN SPINDLE-STEPS.'

To all persons to whom these presents ma/y come:

Be it known that we, GEORGE WILLIAM KNIGHT and GEORGE DRAPER, of Hopedale, of the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in the Bolsters or Bearings of the Spindles of Spinning-Machines; and do hereby declare the same to be described in the following specification and represented in the accompanying drawing, of which- Fignre 1 is a top view,

Figure 2 a side elevation, and

Figure 3 a vertical and transverse section of one of our improved holsters.

In spindle-holsters provided with a conic frnstum raised within the oil-reservoir and around the spindle.- bearing it has been found that when the top of the cone ofthe oil-chamber or reservoir is below the level of the upper edge of such chamber there is a great liability of waste of oil in consequence of the chamber, while being supplied with oil, being made to receive oil to a depth greater than that of the cone, whereby all that oil which may be above the cone will soon be discharged 'through the mouth of the cone and run down upon the spindle and be wasted.

In constructing our improved bolster we arrange the upper edge a ofthe oil-reservoir B level with the top ofthe cone O, or slightly below the said top.

Furthermore, we arrange within the oil-reservoirand around the cone C, and so as to extend abovethe cone and the top of the reservoir and iit around the spindle A, in manner as shown, a hollow cone or dome, D, having one or more apertures made through it near its base, or having such base raised a short distance above the bottom of the reservoir, in order that oil, when poured into that part of the reservoir which is situated outside of the hollow dome, may freely ow into that portion obtint; reservoir which is within such dome.

We also provide the reservoir and dome with an inclined annular cover, E, which rests on the top of dome also performs the'function of protecting the cone and the bearing of the spindle from dirt and extraneous matter liable to gather thereon.

The cone C, as in Richards bolster, will perform" its duty of. aiding in elevating the oil to the spindle while the latter may be in operation.

If desirable, a hollow frustum of felt or a wick may be arranged in or about the cone O, but such is rarely, if ever, necessary.

We make no claim to the spindle-bolster constructed as represented -in the United States patent No. 92,647, dated July 13, .1869.

Furthermore, we have to remark that by extending the dome D up into or through the cover F, in `manner as shown, snchcover is prevented from being caught and revolved by the spindle, especially while being raised upward for the purpose ofenabling oil to be poured into that part of the reservoir which is outside of the dome. Thus by means of the dome we not only protect the part C from loose fibrous matters, but preserve ythe cover F from being caught and`revolved by the spindle while the latter may be .iu revolution.

What we claim as of our invention is as follows:

1. The combination and arrangement of the hollow donne D with the oil-reservoir B, and with the fru-stum disposed in the latter, as set forth. i

2. -In the bolster, as composed of the oil-reservoir B, and the frustum C, and the dome D arranged therein, the oil-reservoir and the cone or frustum c, as constructed, with their .upper edges on a level, or with that of the cone or frustum arranged above that 4of the` reservoir, as described.

3. The dome as arranged within the oil-'reservoir of the bolster and around the spindle-bearing, substantially as described. 4. 'lhe combination and arrangement of the oil-reservoir B, the cone or frustum O, the dome D, and the cover or cap E,.all being substantially as described. GEO. W. KNIGHT. GEORGE DRAPER. Witnesses:
